GASK'ET CHECK VALVJE.

Application filed April 5,

To all 'whom it may sondern:

Be it known that I, JAMES H. BABRETT, a citizen of the United States, residing at Beggs, in the county of Okmulgee and State of Oklahoma have invented a new and use ful Gasket heck Valve, of which the following is a specification.

This invention relates to water circulating systems for internal combustion engines, and more particularly to check valves to be located therein.

The object of the invention is to provide a gasket carried check valve to be used in motors in which water is used to circulate through the engine to prevent overheating, said valve being so constructed and located as to nsure the circulation of the water and prevent back pressure due to steam.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of Construction herenafter described and claimed, it being understood that changes in the precise embodiment of the invention heren disclosed may be made within the scopo of what is claimed without departing from the spirit of the nvention.

In the accompanying drawings:-

F ig. 1 represents a perspective view of a Ford car engine equipped with this improvement.

Fig. 2 is a front elevation of the gasket embodying the invention Fig. 3 is an enlarged detail sectional view taken on the line 3-3 of Fig. 1.

Ford motors are received fromthe factory with no checks between the motor and the radiator and consequently water from the radiator does not circulate through the motor at all times, but is frequently forced back into the radiator from' the bottom by steam pressure from the motor. This results in the boiling of the water and overheating of the engine. This nvention is designed to be installed in the inlet between the water jacket of the motor and the radiator whereby the water is forced back into the radiator from the top of the motor. This prevents overheating of the motor and in freezing weather is an aid to prevent the water freezing in the radiator since the water always freezes in the bottom of the radiator first and by causing this water at 1923. seriarNo. camet.

the bottom of the radiator to continuously circulate the freezing is prevented.

In the accompanying drawings, an engine 1 such as is ordinarily used in Ford cars is shown having the usual water jacket 2 connected by a coupling 3 at the front portion thereof with the radiator 5 while a return pipe 4 connects the bottom of the radiator with the water jacket at the side of the engne.

The gasket 10 which constitutes this invention is located between the coupling 3 and the front end of the water jacket and is constructed in detail as shown clearly in Fig. 2 comprising the usual copper plates having a suitable ller between theni and which are provided in their ends with apertures 11 to receive the bolts which connect the couplng with the water jacket.

This gasket 10 has the usual opening 12 therein here shown surrounded by a seat 13 having mounted thereon a flap valve 14. This valve 14 is hingedly connected as shown at 15 and has an opening` 14 at a point dianetrically opposite the hinged portion, the size of which is adjusted by means of a rotatable plate 16 here shown in the form of a disk journaled centrally at 17 to the valve;

This plate 16 is equipped with a finger grip in the form of a lug 18 to facilitate its rotation and has a plurality of apertures 19 and 19 to vary the size of the opening in the valve which opening is designed to permit water to drain from' the radiator into the engine jacket when desired.

This valve is niounted to swing outwardly toward the radiator so that the water in the engine will be forced out through the ra diator and prevented from flowing back should steam be generated. i

Another one of these check carried gaskets is shown 'at 20 located between the inner end of the pipe 4 and water jacket of the engine and opens inwardly permitting the water to flow from pipe 4 into the water jacket of the engine and prevents its re turn, thus insuring a continuous circulation of the cooling fluid and preventing stean from entering pipe 4 from the engine water jacket.

Various changes in the form, shape, proportion and other minor details of construction may be made without departing from the prncple or sacrficng any of the act Water jacket; of gasket carred check valves Vantages of the claimed inventon. located between said couplng and jacket and I clamzsupply pipe and jacket, the valves in said The combnaton With an engine having a gaskets opening in the same direction.
